A Application led December 27, 1910. Serial No. 599,363.

'To all whom 'it mag/concern.-

Be it known that I, GEORGE THRII.-

KILL, a citizen of the United States, residing 5 vat Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Grease- Cups, of which the following is a specifica-A tion.

My invention relates to improvements in It relates particularly to grease cups in which a-screw threaded closure is fitted ina threaded opening through which the cupis filled with grease. l i

The object of my invention is to lprovide a simple andefficient means 'for limiting the outward movement of the closure in the filling opening, `so that the closure will not work out.

In the accompanying drawings illustrative of inyinvention, Figure 1 is a side elevation of the preferred form of my invent-ion, showing the bail in the locking position.' Fig. 2 is a side elevation looking in a direction at right angles to the direction in which the device is viewed, as shown in Fig. 1. Fig. 3 is a central vertical section on the dotted line an?) of Fig. 2.` Fig. t is a top View.

Similar reference characters denote similar parts.

1 denotes an ordinary grease cup, such as employed to feed the bearings of engines `and other machinery. The cup is provided with a screw threaded opening 2 in which is remov. bly fitted a screw threaded closure ,k

which also serves as a `piston to force the grease outwardly through the discharge opening 4.

Ordinarily much annoyance'is occasioned .by reason of ,the closure 3 working out of the opening 2 owing to the jarring to which the cup is subjected. To 4prevent the closure working out I preferably provide a locking member for limiting the outward movement of the closure Bin the opening 2. This locking member is preferably aninverted U shaped bail 5 the two parallel arms of which are provided with horizontal holes through which respectively extend horizontal screws or pins 6 which -are mounted in threaded holes disposed in diametrically opposite pofsitions in the outside'of the cup 1. -The pins orscrews .6 serve as pivots upon which the bail-5 may swing to and from lthe locking position shown inFig. 1 and insolid lines i `in Fig. 2. When this position the hori- -pin 8 which is adapted, when the bail is in ent, is

zontal portion of the bail 5 is disposedso as to limit theoutward movement of the closure 3, thereby preventing detachment of the closure from the cup. To releasably lock the bail 5 in the locked position, shown in Fig. 1

any suitable meansmay be provided. For

this' purpose I have shown one arm of thebail 5 provided with va. resilientextension 7 having scuredto it an inwardly extending the locking "position to enter a recess y9 provided' in' the outer side of the cup 1. The

length of the pin Sis such that when the bail is` being' swung from the position shown in dotted lines in Fig. 2 toward the position shown in solid'lines in said figure the pin 8 will strike the cup 1 and force outward the recess-9, at which time the 'said resilient portion lwill force the pin into the recess 9, thereby locking the bail in the locking position. To release the Aloailit is but necessary to spring outward lthe resilient part 7 sufli ciently to withdrawthe pin 8 frointhe recess 9, after which the bail may be swung to the position shown indotted lines in Fig. 2. IVhen in theposition shown in' dotted lines in Fig. 2 the bail will not obstruct the removal of the closure 3 Afor the purpose of lilling the cup 1. It will be noted that the'bail 5 is normally disengaged from the closure 3, so that the closure may be readily turned to force grease from the cup.

I do not'limit my invention to the structure Vshown and described as many modifications, within the scope of the appended claims, from the spirit of my invention.

Having lthus described lmy invention, what I claim and desire to secure by LettersIat- 1. A grease cup having a screw threaded opening throughwhich the cup is filled, a

.screw threaded closure fitted'in said opening, the cup having a peripheral recess, a resilient member pivoted to the cup so as to swing to and from a position in'which vit will limit the outward movement of theolosure, and a pin carried by 'said member and adapted to enter said recess when the niember is in said position for locking the membei` in said position. ,A 2. A grease cup having a screw threaded opening` through which the kcup is'l filled, a screw threaded closure fitted in said opening, a bail pivoted to the cup so as to swing may be. made without departing .resilient portion `7 until the pin is over the ioo fo. anlclfi'orn zii-position in which it will hold name to this specification in presence of two the clone from working out of said opensubscribing Witnesses,

ing, the bail having a resllient portion and a Y device carried by said resilient portion for GEORGE W THRAILKILL' 5 engaging. tno cp'j to hold the bail in said po- Witnesses:
